Abstract

A robust header compression processing method and a robust header compressor are disclosed. The method includes: a compressor processing a plurality of data packets at the front of a packet flow by using an Internet Protocol (IP) identifier random behavior pattern, and determining an IP identifier behavior pattern according to characteristics of IP identifiers in the plurality of data packets at the front; and the compressor processing subsequent data packets of the packet flow according to the determined IP identifier behavior pattern. With the robust header compression processing method and the robust header compressor, waste of wireless resources can be avoided, and a utilization rate of the wireless resources can be enhanced.

Description

TECHNICAL FIELD

[0001] The present document relates to the field of mobile communication, and especially, to a robust header compression processing method and a robust header compression algorithm in a robust header compression processor.BACKGROUND OF THE RELATED ART

[0002] Due to the limitation of physical conditions, when compared with wired links, wireless links in a mobile communication system have a lower transmission rate and a higher bit error rate. In order to make effective use of the limited wireless channel bandwidth resources, the Robust Header Compress (ROHC) technology is introduced. The core of ROHC is to use the information redundancy between packets of service flow to transparently compress and decompress information in packet headers between directly connected nodes. The ROHC technology is described by the RHC3095 document of Internet Engineering Task Force (IETF). But compression and decompression of an Internet Protocol (IP) header is not defined in the document, t...
